In the RAID System, all the hard disk drives (SAS/SATA) or SSD must have the same capacity, interface
type, and rotational speed.
•
Use RAID System Configuration utility (WebBIOS) to build a RAID System. For more information, refer to
the manual supplied with the optional RAID Controller (N8103-172/173/174/168).
Important
•
Do not change the mode to hibernate while building a RAID System.
•
Build a Disk Array in the RAID System using hard disk drives that have the same
specifications (capacity, rotational speed, and standard).
